In chapter 13, Van Til argues that no knowledge or reasoning can be separate from the Christian God. He claims that revelation is valid because its absolute truth isn't denigrated by our cognitive faculties. This argument ultimately leads to the same subjectivism we see in materialism. He assumes the validity of his paradigm from the beginning. In doing so, Van Til fails to construct a coherent argument. I left the link to his book for all to read. Van Til's works are the foundation of presuppositional apologetic. It's an interesting text in that it extremely flawed.
